Facts
- A police officer stopped a car in Sunnyvale, California, around 2:40 a.m. for equipment violations (burned-out headlight and license plate light).
- The car contained six men, including Robert Clyde Bustamonte as a passenger.
- The driver could not produce a driver’s license; another passenger, Joe Alcala, produced a license and said the car belonged to his brother.
- After backup arrived, officers asked the occupants to exit the vehicle.
- An officer asked Alcala for permission to search the car; Alcala responded affirmatively and assisted by retrieving keys and opening compartments.
- Officers found stolen checks under the rear seat; the checks were introduced at Bustamonte’s trial for possessing checks with intent to defraud.
- Bustamonte was convicted; state appellate courts upheld admission of the checks on the ground that Alcala’s consent was voluntary.
- Bustamonte sought federal habeas relief; the district court denied relief, but the Ninth Circuit reversed, requiring proof that the consenter knew he could refuse consent.
Issues
- Whether the Fourth and Fourteenth Amendments require the State, to justify a consent search, to prove that the person consenting knew he had the right to refuse consent.
- Whether voluntariness of consent is determined by a totality-of-the-circumstances test rather than a “knowing and intelligent waiver” standard.
Decision
- The Supreme Court reversed the Ninth Circuit in a 6–3 decision.
- The Court held that the State must prove consent was voluntary under the totality of the surrounding circumstances.
- The Court rejected a categorical requirement that the State prove the person consenting knew of the right to refuse.
- The Court treated knowledge of the right to refuse as a relevant factor, but not a prerequisite to valid consent.
- Applying the totality test, the Court concluded the record supported the state courts’ finding that the consent was freely and voluntarily given; Bustamonte’s habeas claim therefore failed.
Legal Principles
- A consent search is reasonable under the Fourth Amendment if consent is voluntary, determined from the totality of all surrounding circumstances.
- Voluntariness is a fact question focused on whether consent was the product of an essentially free and unconstrained choice, rather than duress or coercion (express or implied).
- The “knowing and intelligent waiver” standard applicable to certain trial-related rights does not govern Fourth Amendment consent searches.
- Knowledge of the right to refuse consent is one factor bearing on voluntariness, but the government is not required to prove such knowledge to validate a consent search.
Conclusion
The Court held that consent searches are constitutional when consent is voluntary under the totality of the circumstances, and it declined to require the State to prove that the consenting person knew he could refuse consent.
